A) $\left[ \begin{array} { l l l } 1 & 3 & 1 \\ 1 & 3 & 1 \\ 3 & 3 & 3 \end{array} \right] + \left[ \begin{array} { l l l } 1 & 0 & 1 \\ 1 & 0 & 1 \\ 0 & 0 & 0 \end{array} \right] = \left[ \begin{array} { l l l } 2 & 3 & 2 \\ 2 & 3 & 2 \\ 3 & 3 & 3 \end{array} \right]$

B) $$\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { l l l } 1 & 1 & 1 \\1 & 1 & 1 \\1 & 1 & 1\end{array} \right] = \left[ \begin{array} { l l l } 2 & 3 & 2 \\2 & 3 & 2 \\3 & 3 & 3\end{array} \right]$$

C) $$\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { r r r } 0 & - 1 & 0 \\0 & - 1 & 0 \\- 1 & - 1 & - 1\end{array} \right] = \left[ \begin{array} { l l l } 1 & 2 & 1 \\1 & 2 & 1 \\3 & 2 & 2\end{array} \right]$$

D) $$\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { r r r } 1 & - 1 & 1 \\1 & - 1 & 1 \\- 1 & - 1 & - 1\end{array} \right] = \left[ \begin{array} { l l l } 1 & 2 & 1 \\1 & 2 & 1 \\3 & 2 & 2\end{array} \right]$$
